Description

Reinforced auxiliary frame of loader

Technical Field

The utility model relates to a loader technical field specifically is a strenghthened type loader sub vehicle frame.

Background

The frame system of the loader consists of a front frame, a rear frame, an auxiliary frame and a middle articulated shaft, bears most of the weight of the whole loader, and also bears the force and the torque transmitted by each assembly, so that the frame has enough strength and rigidity. The rear frame is connected with the rear drive axle through the auxiliary frame. The sub-frame is an important load-bearing member of the loader as a connecting structure for connecting the rear frame and the rear drive axle, and bears the entire load of the rear portion of the loader and the impact force generated during the entire operation, and therefore, the sub-frame must have sufficient strength and rigidity.

The existing structure has the defects of poor manufacturing manufacturability and high production cost due to more component parts, more welding nodes and large welding amount; the auxiliary frame bears complex external impact force during working, and when the working condition is severe, the problem of fatigue cracking easily occurs at the welding seam.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a strenghthened type loader sub vehicle frame to solve the problem that proposes among the above-mentioned background art.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a strenghthened type loader sub vehicle frame, includes the backup pad that two intervals set up and is located the bridge connecting plate at backup pad front and back both ends, the pinhole has been seted up at the backup pad middle part, and the grooving has been seted up respectively on the upper portion at both ends, the bridge connecting plate includes the fixed plate at main part and both ends, the grooving cooperatees with the fixed plate, the fixed plate stretches into in the grooving and fixed connection with it, set up the connecting hole that is used for fixed rear axle in the main part.

The upper side and the lower side of the main body are respectively and fixedly provided with a backing plate, and the backing plate is provided with a through hole communicated with the connecting hole.

The left side and the right side of the supporting plate are respectively fixedly connected with flitch plates corresponding to the pin holes, and through holes communicated with the pin holes are formed in the flitch plates.

The cutting groove inclines downwards towards the middle part of the supporting plate.

The cutting groove is provided with a guide groove.

Compared with the prior art, the utility model discloses the beneficial effect who reaches is:

1. the utility model has the advantages of simple structure, small number of parts, and easy guarantee of welding quality by reducing the number of welding seams, thereby improving the overall strength of the auxiliary frame;

2. by arranging the backing plate and the flitch, the structural strength of the connecting hole and the pin hole can be respectively enhanced, the cracking phenomenon caused by long-term stress is effectively prevented, and the service life of the auxiliary frame is prolonged;

3. the grooving is provided with the guide way to backup pad middle part and downward sloping, grooving in to, enables to be connected inseparabler between backup pad and the bridge fishplate bar, has guaranteed the intensity of sub vehicle frame.
